Could Eurofighter become a V/STOL naval aircraft?

Would these carriers receive a naval or V/STOL version of Eurofighter?

No. These ships would remain V/STOL carriers, and a Eurofighter conversion would demand an extensive redesign Britain is not expected to fund.

The enlarged Invincibles would remain V/STOL carriers without catapults and arresting gear. A Eurofighter for these ships would therefore need a much more extensive redesign than an ordinary naval adaptation. Proposals associated with India do not remove the cost of that work. Britain is not expected to fund the rebuild needed to make the aircraft suitable for this carrier fleet.
